A brominated bisacetylenic acid, 18-bromooctadeca-9(E),17(E)-dien-7,15-diynoic acid, has been isolated from the marine sponge Xestospongia testudinaria and its structure elucidated by NMR including 2D homonuclear spectroscopy.
## Abstract Chemical examination of the Chinese marine sponge __Xestospongia testudinaria__ resulted in the isolation and characterization of twelve new brominated acetylenic acids, namely xestospongienols AβL (**1a**β**1d, 2a**β**2d**, and **3a**β**3d**), together with the known analog **4**. The
